Backups from Shadows

A backup of a databank can be taken from a shadow instead of the master databank in situations were optimal performance from the databank must be maintained or when it is desired that the databank be set offline while it is being backed up.

This allows the backup process to proceed without affecting the users working with data contained in the databank.

If a shadow is set offline, the relevant transactions will be written to the online databank but remain in TRANSDB until the shadow is set online again and the transactions can be written to it.

Backups from shadows can be taken by an online backup, using the SQL system management statements.
